#255 Dewatering Residuals from Water Treatment Plant

The second stage of a three stage lagoon system was filling up with solids and they were overflowing to the third stage at this Ohio wastewater treatment plant. Testing indicated a contaminant was present in the biosolids and they needed to go to a landfill. WaterSolve LLC was called in to install a 60′ circumference by 100′ long Geotube® that fit on the bank of the lagoon. A dredge was used to pump the solids from the lagoon to the Geotube® for dewatering. The manager plans on using this process the next time the solids are a problem.
